📌 Why in News?
Friedreich ataxia (FA) has gained attention as a rare inherited neurological disorder for which newer disease-modifying treatment options are emerging. The disease remains an important example of how understanding genetic mutations can guide targeted therapies. Nature: Rare, inherited neurodegenerative disorder affecting coordination and movement.
Syllabus & Relevance
Prelims: Science & Technology — institutions, terminology and factual features connected with the development.
Mains: GS-3 — contemporary application of the relevant syllabus theme.
Current–static link: Revise the underlying institution, policy or concept together with this development.
Why it matters for India
India Produces Too Many Engineers: Why It Needs Better Ones India’s engineering education system has expanded access, but employability remains a concern.
India needs to shift engineering education from quantity to quality.
India has solved access to engineering education, but quality and relevance have not kept pace, and the GenAI era demands a fundamental pedagogical shift.
Static Foundation
Nature: Rare, inherited neurodegenerative disorder affecting coordination and movement.
Inheritance: Autosomal recessive—a person generally inherits defective copies of the relevant gene from both parents.
Gene involved: FXN (frataxin) gene.
Mutation: Usually expansion of GAA trinucleotide repeats in the FXN gene.
This reduces production of frataxin, an important protein involved in mitochondrial iron-sulfur cluster formation.
Consequence: Mitochondrial dysfunction and oxidative stress, leading to progressive damage to nervous and muscular systems.
Common manifestations include ataxia, impaired coordination, muscle weakness, speech difficulties and cardiac complications.
Data, Reports, Cases & Examples
NASA’s Nancy Grace Roman Space Telescope is scheduled for launch on 30 August 2026 aboard a SpaceX Falcon Heavy from Kennedy Space Center, Florida.
After launch, it will travel towards the Sun–Earth Lagrange Point 2 (L2), about 1.5 million km from Earth.
Mission duration: About 5 years, with a potential 10-year goal.
Orbit: Sun–Earth L2, located on the side of Earth opposite the Sun.
Its Wide Field Instrument (WFI) will have a field of view at least 100 times larger than Hubble’s, enabling extremely large astronomical surveys.
It is expected to conduct a microlensing survey of the Milky Way and potentially identify more than 1,000 exoplanets.

Mains Perspective
Background and key dimensions
- Gene involved: FXN (frataxin) gene.
- Mutation: Usually expansion of GAA trinucleotide repeats in the FXN gene.
- This reduces production of frataxin, an important protein involved in mitochondrial iron-sulfur cluster formation.
- Consequence: Mitochondrial dysfunction and oxidative stress, leading to progressive damage to nervous and muscular systems.
- Common manifestations include ataxia, impaired coordination, muscle weakness, speech difficulties and cardiac complications.
- Omaveloxolone is a disease-modifying therapy developed for Friedreich ataxia.
- It acts on cellular antioxidant and stress-response pathways and has shown potential to slow functional deterioration.
- Genetic mutation → defective protein → mitochondrial dysfunction → neurodegeneration → targeted therapy.
- Prelims Trap: Friedreich ataxia is primarily a genetic/mitochondrial disorder, not an infectious disease.
